A cat-back exhaust replaces the piping and muffler from the catalytic converter back, here with dual pipes exiting the truck.

why this one — Outlaw is Flowmaster's loudest, most aggressive line, and this dual-exit version gives a more aggressive stance and tone than their single-exit Outlaw.

where the number comes from

No manufacturer or independent dyno figure found for this specific product. Cat-backs on turbo trucks with a downpipe/tune doing the real work typically carry no standalone gain claim; sound/tone is the primary value prop.

how we estimated it

Estimated from comparable claims: MBRP ~+5 whp; Corsa +12; Flowmaster 11; Flowmaster 18
